Go1编译器如何工作？

Question

I've been dabbling with Go for about a month for a school project and I noticed the go/ast, go/token, go/parser, etc. packages in the src/pkg/go folder. However, the gc compiler was based on C files located in src/cmd/gc.

My question regards the new go command in Go1 that builds and runs programs: does this tool depend on the packages I referenced above? i.e. if I added a new token to /go/token/token.go, would it be recognized by the new go compiler?

Answer 1

does this tool depend on the packages I referenced above?

The 'go' tool does depend on those packages

if I added a new token to /go/token/token.go, would it be recognized by the new go compiler?

No.
